Umbrella crib cover

ABSTRACT

A cover for the protection of an infant comprises a central hub member which is pivotally connected at one end to an extendable and collapsible support frame made up of link arms and pivotally, flexible connected frame ribs. The ribs reside in channels in an exterior surface covering of mesh cloth or transparent or opaque material. The hub member is connected, at its other end, to a string-like line which extends through an opening on the top of the cover. The line is attached to a handle. With the cover in a collapsed position, the handle is pulled upwards, which causes the attached line and the hub to move upward. This results in the link arms pivoting the frame ribs outward and upward. Upon continued pulling on the handle, the hub is pulled into and secured within the opening, causing the frame and surface covering to become fully extended. The cover forming the resulting enclosed space is lightweight and can readily be secured to a crib or simply placed on a bed, the ground, or other unprotected area. The surface covering is provided with a zippered opening to allow for internal access to the cover. By simply pushing down on the hub when the cover is extended, the cover will be caused to collapse.

BACKGROUND OF THE INVENTION

[0001] A defenseless infant who is placed in a crib, playpen, or a bed or even on a blanket on the floor or ground is susceptible to hazards from the environment. For instance, an infant so positioned may be bothered by a pet, such as a dog or cat. There is also the risk of falling objects on the child. When in the outdoors, a baby is vulnerable to insects and exposure from the sun.

[0002] To account for these hazards, various crib and playpen covers or canopies have been developed. Examples of these are shown in U.S. Pat. Nos. 2,820,468; 3,546,721; 4,945,584; and 6,123,091. However, while these covers provide a measure of protection for infants, they, like most prior covers, require extensive efforts during set-up and take-down. For instance, the '468 and '584 patents require that a number of components laboriously be assembled and then connected to a crib or playpen; and the '468 patent can only be used on an infant enclosure. The covering shown in the '721 patent also must be tightly secured to a crib structure, by the weaving of line around its perimeter. The '091 patent shows a canopy which is foldable and appears to have components which make it heavy and difficult to install and transport.

[0003] It is thus an object of the present invention to overcome the disadvantages and limitations of existing infant protection covers.

[0004] It is an object of the present invention to provide an infant cover which provides an enclosed space for the safety and protection of infants from pets, insects, the outside elements, and other hazards.

[0005] It is another object of the present invention to provide an infant cover which can be automatically and quickly assembled and disassembled.

[0006] It is further object of the present invention to provide an infant cover which is a self-contained unit with inter-connected components, for ease of assembly and disassembly.

[0007] It is another object of the present invention to provide an infant cover which is lightweight and readily transportable.

[0008] It is still another object of the present invention to provide an infant cover which is collapsible for easy storage.

[0009] These and other objects of the invention are accomplished by the present infant protection cover which opens and closes in umbrella-like fashion. It comprises a central hub member which is pivotally connected at one end to an extendable and collapsible support frame made up of link arms and pivotally, flexible connected frame ribs. The ribs reside in channels in an exterior surface covering of mesh cloth or transparent or opaque material. The hub member is connected, at its other end, to a string-like line which extends through an opening on the top of the cover. The line is attached to a handle. With the cover in a collapsed position, the handle is pulled upwards, which causes the attached line and the hub to move upward. This results in the link arms pivoting the frame ribs outward and upward. Upon continued pulling on the handle, the hub is pulled into and secured within the opening, causing the frame and surface covering to become fully extended. The cover forming the resulting enclosed space is lightweight and can readily be secured to a crib or simply placed on a bed, the ground, or other unprotected area. The surface covering is provided with a zippered opening to allow for internal access to the cover. By simply pushing down on the hub when the cover is extended, the cover will be caused to collapse.

[0010] The novel features which are considered as characteristic of the invention are set forth in particular in the appended claims. The crib cover itself, however, both as to its design, construction, and use, together with additional features and advantages thereof, are best understood upon review of the following detailed description with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION

[0022] Protective cover 2 of the present invention comprises central hub member 4. Hub 4 is pivotally connected at one end to four link arms 7, which are in turn each pivotally connected to one of four lightweight, flexibly resilient ribs 8. The lower ends of ribs 8, as shown in FIG. 9, comprise rounded end caps 23. The four link arms 7 and four ribs 8 form the support frame of the invention. The upper ends of each of the ribs 8 are pivotally connected to lower cover sleeve 10. Intermediate cover sleeve 12 is configured to be positioned over lower sleeve 10. Upper cover sleeve 14 is configured to be positioned over intermediate cover sleeve 12. Each of the sleeves 10, 12, and 14, has an opening therethrough, indicated at 11, 13, and 15 respectively, to accept hub 4, when cover 2 is in its fully open, extended position.

[0023] Wire connector 16 extends around exterior channel 9 of sleeve 10 and through holes 38 at the upper ends of each of ribs 8, to secure the ribs to the sleeve. Wire connector 18 extends around exterior channel 5 of hub 4 and through holes 39 at the lower ends of each of link arm 7, to secure the link arms to the hub. As shown in FIGS. 10 and 11, link arms 7 are secured to ribs 8 by rivets 29 or similar connectors, extending through holes 26 through tabs 25 on ribs 8 and corresponding holes 28 through tabs 27 at the upper ends of link arms 7. In this manner, link arms 7 are fully pivotable in relation to hub 4 and ribs 8, and ribs 8 are fully pivotable in relation to sleeve 10 and link arms 7.

[0024] The end of hub 4 which is not connected to link arm 7 is connected to line 20, which may be string, cord, twine, thin wire, or other similar flexible elongated components. When cover 2 is collapsed, as shown in FIG. 2, line 20 extends from hub 4 through openings 11, 13, and 15 of sleeves 10, 12, and 14, and out to the exterior of the cover, where it is connected to handle 22.

[0025] As seen in FIG. 1, cover 2 has exterior surface covering 24 with four channels 40 into which the four ribs 8 are positioned. Surface covering 24 can be of mesh material construction or of transparent or opaque material, depending on the use contemplated. A transparent material, of course, would provide a more enclosed space, but would still permit observation of the infant. An opaque material would prevent exposure from the sun.

[0026] A zipper is provided on surface covering 24, at location 42, which permits internal access to cover 2 through zippered opening 28. As shown in FIG. 5, storage bag 31 with zipper attachment 35 and handle 33, is provided for storage and carriage of cover 2 when in its collapsed position.

[0027] In use, cover 2, in collapsed position, as shown in FIG. 5, is removed from storage bag 31. Once cover 2 is removed, handle 22 of the cover is simply pulled upward, which causes line 20 and hub 4 to also move upward. This results in link arms 7 pivoting frame ribs 8 outward and upward. Upon continuing pulling of handle 22, frame ribs 8 become extended, as shown in FIG. 7, until hub 4 is pulled completely into openings 11, 13, and 15 and is wedged in place within sleeves 10, 12 and 14. This causes link arms 7 to fully extend which bends resilient frame ribs 8 into the downwardly extending, bowed configuration of fully extended cover 2, as shown in FIGS. 3 and 4.

[0028] Thus, the cover forming the resulting enclosed space is automatically opened to form a complete and lightweight enclosure. Cover 2 can then readily be secured, for instance, to crib 50 by means of retention straps 32 and end flap 34, which can be tied onto the crib. Cover 2 is also lightweight enough to allow it to be picked up and placed on a playpen, bed, the ground or other unprotected area.

[0029] By simply pushing down on hub 4 when cover 2 is extended, the hub will retreat through openings 11, 13, and 15 and automatically collapse the entire cover. It can then be returned to bag 31 where it can easily, once again, be stored.
